HARNESS-MOTION FOR LOOMS.

SPECIFICATION forming part Of Letters Patent N0. 290,286, dated December18, 1883. Applicationfiled October 9, 188:2. (No model.)

To all whom, it 17mg/ concern and JOHN W. CLAPP, citizens of the UnitedStates, both of the city and county of New: Haven, in the State ofConnecticut, have invented anew and useful Improvementin'I-Iarness-Motions for Looms, of which the following is aspecification.

Our invention is more especially designed Io for use with small looms,several of which are arranged in line and driven by one main shaftrunning through the whole series of looms. It may, however, be appliedto other descriptions of looms. The object of our` invention is tofacilitate the changing ofthe order of working the hai`nness with theleast possible change in the parts of the harness-motion.

In carrying outour invention we employ a 2o vertical shaft driven by abevel-wheel operated by abevel-wheel of smaller diameter mounted on theshaft for operating the lay -and shuttle motions, which shaft, by meansof gear-wheels and a suitable clutch-motion, is `operated by the mainshaft. Upon the vertical shaft is mounteda series of cams composedl ofiianged cylinders having removable sections so applied between theiianges that when the said sections are arranged in one order they 3oshall produce cam-grooves adapted to operate the heddles so as toproduce plain weaving, while by other arrangements of the sectionscam-courses will be formed adapted to produce four-lcafed twill,gros-grain, or other descriptions of weaving, as desired. The treadlesare pivoted, so as to be capable of swinging in vertical planes, andhave their ends engaging directly with the heddle-frames, and they carrybowls or rollers which run in 4o the cam-courses of the cams on thevertical Vharness-shaft. Thevertical or harness shaft may be variouslyspeeded in relation to the shuttle-driving shaft, according to thenumber of divisions in the cam or number of sections of which it iscomposed.

The accompanying drawings form part of this specification, andillustrate what we conl sider the best means of carrying out the in- Beit known that we, WALTER G. TILLoiuV vention. v

Figure l is a vertical section of so much of 5o a loom as 4willillustrate the invention. Fig. ldis a detail perspective view on alarger scale, showing how the treadles are connected with theheddle-frames. Fig.. 2 is a horizontal section ofthe saine with theupper working 5 5 parts removed. Fig. 3 is a diagram showing the surfaceof one ofthe cams laid out in a plane with its sections arranged toproduce plain weaving. Fig. 4 is a similar diagram, representing thesections arranged to produce four` 6o leaf twill. Fig.5 is anotherdiagram, showing the sections arranged for producing grosgrain. Figs. 6and 7 are perspective views of two forms of sections which we have shownemployed in Figs. 3, 4, and 5. 615

In each of the views similar letters of reference are employed toindicate corresponding parts wherever they occur.

A is the main framing, and B the drivingshaft, which is mounted inbearings a3 c3, formed 7o in the main framing A, and provided with afast driving-pulley, at, and loose pulley a5. Upon the main shaft B ismounted a wheel,

B', which, when connected with the shaft B by means of the doublelclutchL, operates the 7 5 wheel C', mounted on the shaft C, which actuates themechanism for operating the lay D and the shuttlemotion, and imparts mo`tion, as hereinafter explained, to the vertical shaft E, upon which thecams Eil are mounted. 8o The cam Z" of the clutch L actuates the warpstop-motion. The shuttle and warp stop-motion, however, form no part ofthe present application, and are simply referred to in so far as isnecessary to illustrate the present in- S 5 Vention.

The shuttle mechanism'forms the subject of our application for LettersPatent filed June 8, 1881, of which the serial number is 85, 208; andthe warp stop-motion, including the cam 9o L, forms the subject of ourapplication for Letters Patent filed October 9, 1882, of which theserial number is 73,829.

Upon the shaft C is mounted abevel-wheel,

C?, which gears into a bevel-wheel, C3, the body o1' which isbowl-shaped, so as to allow of the free action of the cam Q foroperating the lever q, by means of which the shuttle is actuated.

Upon the shaft E is mounted a series of camcylinders, F, each of whichis provided with flanges eZ cg, between which are placed a series ofsections, ci", so arranged as to form a cam-course, e, adapted toreceive and operate a truck or bowl mounted on the short end c4 of oneof the harness-treadles e', which are pivoted to a vertical bar, A',forming part of the main framing A.

S designates the heddle-frames, to which the ends of the treadles c aredirectly connected in any suitable way. In this example of our inventioneach heddle-i'rame S has projecting from it a lug or ear, s, (best shownin Fig. 1123) in which is a slot, s', and the treadle c is inserted inthis slot and secured by a catch consisting of a spring, s2, and a piu,s, which enters a hole in the treadle. The treadle may be detached bydeiiecting the spring s2 ontward sufficiently to permit the treadle tobe withdrawn from the slot s.

In the drawings, Figs. l, 2, and 3, we have shown our improved devicesarranged for producing plain weaving, in which case the sections c3 arearranged at equal distances apart and alternately on the opposite sidesof the space on each cylinder D?, between the flanges e", so as to forma course c which will give a regular up-and-down motion to the alternatetreadles for every piel: of the loom. The cylinders E, as shown in thedrawings, are arranged with eight divisions and eight sections c, eachof which is secured in the position desired by means of countersunkscrews c, which pass through holes c5 and are received into holes c,tapped in the cylinders Eik. There are sixteen holes, c, shown tapped ineach cylinder E, one-halt` only of which are in use at the same time. InFigs. 1 and 3, the sections c being arranged alternately on oppositesides 'for the production of plain weaving, alternate holes c6 are usedand vacant. In Fig. et the sections e are shown as arranged threetogether on the top side of the cylinder Fj, with one sectioninterspaced on the lower side, so as to form a cam-course which will sooperate the heddles that three heddles will always be up and one down,for the purpose of producing four-leaf twill. Two holes c on the topside and six holes on the lower side are vacant, while the remainder areemployed to hold the sections c in place. Four cams will be required, asin Fifr. 1, all with sections arranged as in Fig. 4. In Fig. 5 we haveshown the cylinder E* with the s cctions c3 arranged two togetheralternately on opposite sides t0 forma cam-course which will so operatethe heddles that two will always be up and two down, for the purpose ofproducing gros-grain, in which ease every alternate two of the holes oneach side are occupied and vacant. Four cainswillbe required, each withthe sections arranged as in Fig. 5. In order to provide for adapting thecams to weave any kind of goods, some of the sections must have theirends inclined in opposite directions, as shown in Fig. 6, while othersof the sections must have both their ends inclined in the samedirection, as shownin Fig. 7. IThe reason for this will be seen from thedrawings. In Fig. 4, where the sections are arranged three together 011one side, the middle section of the three is reversed, so that thesections will form a continuous wall or side to the camcourse, and forthis form of cam each section should have its ends inclined in reversedirections. In Fig. 5,where the sections are arranged two together, itwould be impossible to form a cam-course of the sections shown in Fig. 6alone, and we must use for each pair a section of the form shown in Fig.6 and a section of the form shown in Fig. 7. The manner of combining thetwo sections of the forms shown in Figs. 6 and 7 so as to properly formthe cam-course will be understood from Fig. 5. As before stated, thecylinderE* has eight divisions, and the length of each periphericalsection from the middle of the incline at one end to the middle oi' theincline at the other end is exactly equal to one of the divisions of thecylinder or to one-eighth of its circumference. The sections cantherefore be easily arranged to form cam-courses of a. number of forms.Other number of divisions of theeylinder and other number of sections ccan be employed, so long as the number is made to agree with the motionsof the shuttle and lay.

XVe are aware that it is not new to operate treadles by means of cams ona vertical harness-shaft, and we are also aware that it is not new toprovide a cam for operating a heddleframe with removable sections, s0that by different arrangements of the sections the movements of theheddle-frame may be varied; hence we do not claim these features,broadly, as of our invention.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

l. The combination,wth theheddle-frames of a loom, of a verticalharness-shaft, earns on said shaft having grooved peripheries,treadlespivoted so as to swing in vertical planes, having their ends engagingdirectly with the heddle-frames, and provided with bowls or rollersruiming in the grooves of said cams, and means for operatingsaid shaft,substantially as shown and herein described.
